You stick your 6 months old in a day care with 15 other little ones. No one talks to them, they just sit in their cribs. The mother picks them up after work, and is probably too exhausted to be patient, then puts them to bed.
This plays out everyday until Kindergarten.
No wonder the kid, esp the boys, are not talking by the time they’re 3 or 4.
Besides if you do that you miss everything until they are able to make their first step. Why would you want to give this joy to a stranger?
